Application led August 21, 1923. Serial No. @that To all whom t mayconcern.'

Be it known that I, ALEXANDER S. MAN- DEL, a citizen of the UnitedStates, residing in the city of New York, in the county of f1 New Yorkand State of New York, have invented a new and useful Improvement inSoda-Water Fountains, of which the following is a specification. I Myinvention relates to a soda-water fountain, especially to a fountain ofthe .class in which the beverages are automatically mixed within theapparatus and in which they are automatically dispensed upon the depositof proper coins, and it consists in the combinations, arrangements, andconstructions hereinafter described and claimed.

My inventionrcontemplates the provision of a fountain of the classspecified, adapted .to contain as independent units a plurality ofdifferently flavored syrups of the character commonly employed insoda-water beverages, adapted to contain for each unit a relay tankforthe aerated water and a mixing chamber or tube in which a predeterminedquantity of syrupand aerated water are mixed as dispensed, and adaptedfurther to contain a feed coil having connection with all of the relaytanks for supplying the latter with aerated water.

The invention also aims to provide a neat, attractive and compactstructure, rovided with properly drained chambers or holding ice to keepthe syrups and aerated water at a low temperature so that cool,refreshing beverages may be ready for dispensing at all times.

rllhe invention also contemplates the pro.- vision for each unit of ahand-lever cornbined with a coin-receiving tilt bar, so constructed andarranged that the hand-.lever cannot be operated and the beverage cannotbe dispensed except u o n the deposit of the coin required to pay or thebeverage.

A still further object of the invention is the provision in connectionwith each unit of a container for carrying pa er drinking cups, of whichone is delivere to the customer each time he de osits a coin to purchasehis drink, and a so for the revision for each unit of a cash drawer foru timately receiving the deposited coins.

One of the many possible' embodiments of the invention is illustrated inthe accompanying drawings forming part of this application and rea (hltFig. 1 is a vertical section of an embodiment of my soda-water fountain,sh the arrangement and relation of the 'compartments, units, feedingcoil and operating mechanism; 0

My soda-water fountain, as herein illustrated, embodies in constructionconcentric cylindrical vessels 10 and 11 having an annular compartmenttherebetween and having a common bottom 12, the side of the outer t@cylinder 10 extending for a distance below the inner cylinder 11 andbeing provided at spaced intervals with vfeet 13 on which to stand.rllhe bottom 12 for the full end area of the inner cylinder 11 isprojected down- M wardly in the form of an inverted cone 111 for thepurpose of conducting water into a drain pipe 15. A distance below theirtop endsthese vessels are provided with a hori- `zontal partition 16thereby dividing them ad into upper and lower comparents, of which thelast mentioned compartment designated'by the numeral 17, is intended tobe filled with sawdust or other substance suitable for insulating theinterior of the at inner vessel against the t nsmission of heat from theoutside. The nnular space above compartment 17 is divided by the radialpartitions 18, 19 and 20 into three equal syrup compartments, 21, 22 and23. t Above the bottom 14, the inner vessel has a perforated horizontalpartition 24 to provide-a drainage chamber 25, and an ice receivingchamber 26 in which is disposed a coiled pipe 27 for the aerated water,one end t 28 of said coil extending outwardly through the sides of thevessels to connect with a source of supply and being provided with anexterior sto -cock 29 whereby to control the inflow of t e aelwtedwater. The other tra end of the coil is branched to conduct the aeratedwater t'o the diderent relay tanks to be hereinafter described.

Spaced about the outer vessel so as to surround the syrup compartmentsand a portion of compartment 17 is built an exterior wall 30 to form acompartment 31, designed to receive sawdust or other insulating materialto prevent the transmission of heat. To the top end of the wall 30 ishingedly enga-ged at 32 a cap 33, designed to form a top closure for theentire structure as shown, said cap comprising a compartment for holdinginsulating material. Set in the horizontal partition 16 is a perforatedice supporting tray 34 formed with inward deformations 35 to clear therelay tanks 36 and formed also with a downwardly offset bottom 37 toreceive the drippings from the tray and direct them through an outlet 38into a drain pipe 39 which extends downwardly through the horizontalpartition 24 and discharges into the compartment 25.

There are, in the present embodiment, as clearly shown in Fig.` 2, threeaerated water tanks 36, one belonging to each syrup compartment andarranged on the inner side thereof in circular series within the icecompartment 40.. lAs best illustrated in Fig. 3, the relay tank ispreferably made in cylindrical form and opening through its bottom wall41 is a branch 42 of the coil 27. Where the branch42 discharges into therelay tank there is provided a conical valve seat 43 with whichcooperates an inverted conically shaped valve 44 attached to a valvestem 45 that extends vertically through the tank and also through agland 46 provided in the removable top wall 47 thereof. Secured on theupper end of the stem is a block 48 and encircling the stem is a spring49 tending normally to force the stem upwardly and to unseat the valve.FiXed on the stem interiorly of the tank isla conical stop 50 adapted toco-l operate with a seat 51 whereby to limit the upward movement of thestem. Leading downwardly from the tank and extending outwardly throughthe walls of the vessels is a pipe 52 which terminates in a downturneddischarging nozzle 53.

The tank is supported on a projection 54 provided on the side wall ofthe inner casing, and which also extends' into the syrup compartment forthe support of a cylinder 55 in which is arranged a piston head 56attached to an upwardly extending piston rod 57 whose upper end ispivotally engaged at 58 with a rocker bar 59 fulcrumed at 6() to astandard 61 secured on the to end of the outer vessel. To the bottom othe cylinder 55 ybelow thel iston head is secured a valve casing 62 whicforms the upper end of a suction pipe 63 that extends downwardly intothe syrup and terminates adjacent the bottom of the syrup compartment.In valve casing 62 is disposed a ball valve 64 and threaded into thecylinder and having a discharge opening 65 is a plug 66. Ball valve 64coopcrates with a seat 67 provided in its casing and is normally held inits seat by a push lis disposed a valve 72 adapted to cooperate with aseat 73 formed at the inner end of thechamber, said ball Valve beingnormally held in its seat by a` push spring 74. A small quantity ofsyrup having been drawn into the cylinder as hereinbefore described,the. piston head on descending forces it out through the openin 69,chamber and pipe 7l into pipe 52, the all valve 72 being forced from itsseat to permit this discharge, while the other ball valve 64 underpressure is tightly seated thereby preventing a return ot.

the syrup into pipe 63.

Formed on the exterior portion of the pipe 52 is an enlargement 75 inwhich is seated a rotary valve 76 having a central opening 77therethrough. For operating this valve. one end of a link 78 ispivotally connected thereto, while the other end is pivotally connectedto the vertically extending operating rod 79. The outer end of therocker bar 59 bears continuously on the upper end of the operating rod79. At its inner or rear end the rock bar is provided with a spring arm80, adapt ed when the rock bar is moved into the position shown toengage the top endof valve stem 45, moving the stem downward andpositively seating the valve 44 against any inflow of the aerated water.Simultaneously with this action, the piston head is moved to the bottomof cylinder 55 causing the discharge ,of a small quantity of syrup intothe pipe 52 wherev it will mix with the aerated water behind the valve76. When the valve 76 is closed against the discharge ot the contents ofpipe 52, the valve 43 is unseated Vpermitting the aerated water togather in the medica side wall of the outer vessel below the projectinginsulatin wall 30, a casing 81 designed to house tie mechanism forcontrolling the up and down operation of the rod 79, and to accommodatein its bottom por tion a coin-receiving drawer 82. As shown in Fig. 4,there is pivoted at 83 to the lower end of rod 79 an operating foot orhand lever 84 which is fulcrumed on a fixed pin 85. To the rear of thepin 85, there is pivoted to this hand lever at `86 for free swingingmovement a tilt bar 87 the forward end of which is formed to comprise ahead 88 adapted to receive a co-in as 89 as it falls from the coin chute90, said tilt bar .nor- Inally maintaining itself in horizontal positionby reason by being weighted at 91 on its opposite end. Adjacent thepivot 86 the tilt bar is formed with an u-pwardly and laterallyprojecting lug 92 adapted' on its downward swing to engage over the topside of lever 84 and thereby to arrest its further downward movementuntil the lever 84 is depressed, the extent of movement thus permittedby thisarrangement of the lug being merely sufcient to permit theweighted end 91 to clear a stop 93 forwardly projecting.

from the outer vessel, but being insufficient to allow the coin 89 toroll from the head.

88. When, under this construction, the lever 84 is depressed to actuaterod 79 and open valve 76, the tilt bar V87 is obviously carried withsaid lever until it assumes approximately a vertical position todeliverthe coin into the chute 94 from which it falls into the drawer 82. Now,if the lever 84 be depressed when there is no coin in the head 88, theweighted end of the tilt bar as it is carried upwardly in an arc aboutthe fulcrum 85, will engage the stop 93 and the lug 92 will engage thelever 84 thereby lockin said lever and preventing the actuation o rod 79for the opening of valve 76. A pull spring 95, which is connected withthe lever 84 forward of the fulcrum and with the fixture 96 secured tothe outer vessel, normally holds said lever in position to be depressedand replaces it after each operation.

The coin chute 90 depends from a housing 97 (Fig. 1) secured to the topend of the wall 30 of the insulating compartment, and therein connectswith a coin slot 98 into which the customer drops his coin. The housing97 contains the mechanism whereby, on the insertion of coin, to permitthe cus tomer to obtain a paper drinking cup as 99 from the stackincased in the glass housing 100 upstanding from housing 97. A

ledge 101 is provided below the-discharging nozzle 53, for the suitablesupport of the paper'drinking cup while it is beingv filled.

ln the operation of my apparatus, the customer on the selection of thesoda desired, inserts his coin in the coin chute, actuates the lever 102(Fig. 1) and receives his paper through which syrup drinking cup. Themomentum of the falling coin swings the tilt lever as hereinbeforedescribed, so as to permit the depression ter, it being noted in thisconnection that the opening 77 in valve 76 is preferably smaller thanthe diameter of the pipe 52 in order to cause an intermixing of thesyrup and the aerated water before passing through the valve. Inpractise, each housing 97 will carry the name of the soda to be obtainedat that place. A lid 103 fitting on the top of ice compartment 40 may bereadily removed to replenish the ice therein. Both the lid 103 and theice tray 34 must be removed in order to replenish the ice in the coilcompartment 26, which is the larger compartment and obviously shouldbeffilled before filling the upper compartment 40. Lids may be providedto cover the syrup compartments, the same to be readily removable whenthe syrups are to be replenished.
